Magnetic spinner device with reels in a lower housing with a removably attachable lower portion

ABSTRACT

A magnetic spinner device using an impeller system to disperse heat and stir contents there-above is disclosed herein. A motor turning the impeller is offset from a center line extending vertically through the device. The impeller, however, is centered with fan blades pushing air downwards as heat rises from a heat source placed there-below, such as between legs which support the impeller and bowl of the device, the bowl being used to hold a flask and/or substances to be heated. The turning of the motor is translated to the turning of the impeller by way of two reels connected by a belt and placed within a lower housing with a removably connected lower portion. In this manner, the electric parts (the motor) and spared the brunt of the heat by being off-center while the heat rises upwards. The simplification of parts leaves less points of potential failure compared to the prior art as does the movement of electric parts away from being above a heat source.

FIELD OF THE DISCLOSED TECHNOLOGY

The disclosed technology relates generally to distillation and, morespecifically, to impeller systems.

BACKGROUND

Distillation or fractional distillation is carried out by heating asolid or liquid and removing gaseous vapors that are expelled therefrom.This is typically carried out by raising the temperature and boiling offfractions of the solid or liquid based on their differing boilingpoints. Separated compounds are removed from a distillation apparatusinto an attached condenser in order to be converted from gas into asolid or liquid. Sometimes, however, the condensation process can beslow and/or less than precise when the solid or liquid is heatedunevenly. The heating process may be made more effective by means ofstirring, but this is an impractical solution for distillation on alarge scale.

Therefore, there is therefore a need for a system which heats solidsand/or liquids efficiently and evenly without requiring humanintervention.

SUMMARY OF THE DISCLOSED TECHNOLOGY

An impeller system of embodiments of the disclosed technology has afirst housing with a lower spindle. A portal within the first housinghas a narrower middle section between two wider sections, and has alower indented section within a raised border. The impeller systemfurther has a first reel and a second reel rotatably connected to eachother by way of a belt, with the lower spindle extending through aportal within said first reel. The first reel, second reel, and belt arein a second housing with a removably attached lower portion. Inembodiments, the lower spindle extends from under the narrower middlesection.

“Spindle” is defined as a device in a shape of a cylinder and/or in ashape of multiple cylinders stacked such that all of the cylinders haveaxis in a same direction, or as a device with a slender and round shaftwhich turns and/or on which something else turns. “Reel” is defined as acircular and/or elliptical, rotatable device around which a flexibledevice, such as a belt, is wound. “Belt” is defined as a continuous bandof flexible material which transfers motion from one device, such as areel, to another such device. “Removably attached/attachable” is definedas capable of being attached and detached at least 1000 times withoutbecoming substantially significantly deformed.

The second reel, in some embodiments, is rotatably attached to a spindleof a motor, such that rotation of the spindle of the motor causes thefirst housing to rotate by way of the second reel, said belt, and saidfirst reel. “Motor” is defined as a mechanical and/or electronic devicewhich supplies motive power, such as by way of a turning spindle.

The second housing, in embodiments, is abutted against a spacer. Thefirst housing, in some versions, is abutted against the spacer and is onan opposite side thereof relative to the second housing. In someembodiments, the spacer and the second housing are removably connectedto each other so that both remain in place relative to one another whenthe first housing, which passes through the spacer, rotates. “Spacer” isdefined as a device which maintains a space of at least 0.1 milimetersbetween at least two other device.

The spacer, in various embodiments, has a central portal through whichthe spindle of the first housing extends, and further has four portalsequi-spaced from the central portal. A distance from a central point ofthe central portal to a central point of a portal of said four portalsmay be substantially greater than a longest horizontal extent of thesecond housing.

The second housing, in various embodiments of the disclosed technology,further has a top side with a lip. The lip, in embodiments, forms aunitary structure with a floor having a first portal therein. A spindleof the motor is substantially centered with respect to the portal of thefloor of the second housing. The lip, in various embodiments, furthersurrounds a second portal larger than said first portal. “Lip” isdefined as a portion of a device, the portion having at least one flatportion and at least one curved portion, the portion further beingfunctionally connected to a planar section with a length greater than aheight of the portion.

“Circumference” is defined as “measure of a length of a circular orovoid enclosing boundary of a named part of the device describedherein”.

Stated differently, an impeller system of embodiments of the disclosedtechnology has a first housing with a lower spindle and a second housingwith a removably attached lower portion. A portal within the firsthousing has a narrower middle section between two wider sections, and alower indented section within a raised border. A planar section of theremovably attached lower portion of the second housing has a thicknesssubstantially equal to a thickness of a functionally connected floor ofthe second housing. The lower portion of the second housing, whenremovably connected thereto, substantially abuts a sidewall of thesecond housing and the floor of the second housing. Thus, a space in aplane of the functionally connected floor of the second housing which iscircumscribed by an edge of the floor and the sidewall of the secondhousing is substantially filled.

A bowl, in various embodiments, is centered above the first housing.

The first housing, in embodiments, is centered above a first reel. Whenthe first reel is placed within the second housing and the lower portionthereof is removably connected thereto, the first reel is locatedvertically above a planer extent of the removable lower portion.Furthermore, when the first reel is placed within the second housing andthe lower portion of the second housing is removably connected thereto,a second reel may be located vertically above a planer extent of thefloor of the second housing. A spindle of a motor, in some embodiments,is substantially centered below the second reel.

In various embodiments of the disclosed technology, a part of a legpasses through each of four portals of a spacer located between thefirst housing and the second housing, each leg being elongated in avertical direction. Four caps, in some embodiments, abut an upper sideof the spacer and hold a respective leg to a lower side of the spacer.Each respective cap, in embodiments, has a respective spindle extendingupwardly there-from.

Each said spindle, in some embodiments, is threaded. Each threadedspindle may be removably screwable into a respective hole on a lowerside of the bowl.

In embodiments of the disclosed technology, the impeller also includes aplate and two magnets abutted there-against. The plate may besurrounded, at least in part, by the lower indented section of the firsthousing. The plate is, in embodiments, centered with regard to the firstreel, and is vertically above the lower portion of the second housing.

The magnets, in some embodiments, are two rectangular prism shapedmagnets abutted against the plate, each located within one of the twowider sections of the first housing. The two wider sections of the firsthousing may be in a shape of a rectangle, with a portal opening formedbetween flanges of the narrower middle section. In various embodiments,an arc corresponding to a circumference of the first reel passes throughboth wider section of the first housing.

In various embodiments, each of the two rectangular prisms has a sidecorresponding to a northern pole of a magnetic field thereof facingupwards towards the bowl and has a side corresponding to a southern poleof a magnetic field thereof facing in an opposite downward directiontowards the second housing and the lower portion thereof. In otherembodiments, each of the two rectangular prisms has a side correspondingto a southern pole of a magnetic field thereof facing upwards towardsthe bowl and a side corresponding to a northern pole of a magnetic fieldthereof facing in an opposite downward direction towards the secondhousing and the lower portion thereof. The plate is magnetized by thetwo rectangular prism shaped magnets.

In some embodiments, the motor is off-center with respect to the bowl,the first housing is centered with respect to the bowl, and the lowerportion of the second housing is centered with respect to the firsthousing.

The first housing, in some embodiments, has fan blades which are closedto a top side of the first housing and open to a bottom side of thefirst housing. A diameter of the fan blades may be greater than a widthof the lower portion of the second housing (the width being in adirection perpendicular to a longest extent of the second housing).

The impeller system may be adapted for placement of a heat sourcebetween the four legs. The heat source may be placed vertically aboveand horizontally offset relative to the motor, and vertically below thelower portion of the second housing. The heat source may further besubstantially centered between the legs. Heat extending upwards from theheat source extends towards the fan blades and is thereby pusheddownwards, causing a more even heating of the bowl while the tworectangular prism shaped magnets rotate with the fan blades.

A flask cover, in various embodiments, is adapted to cover a majority ofa portion of the flask extending past an upper edge of the bowl. Theflask cover may be constructed of an insulating material.

“Functionally connected” is defined as “being inseparable unlessbroken.” “Abut”, “abutted”, and other such terms are defined as “sharinga common boundary there-with.” “North pole” and “south pole”, withregard to magnets, are defined as portions of a magnet which, when themagnet hangs freely, are attracted to/towards, respectively, thenorthern and southern magnetic poles of the globe.

For purposes of this disclosure, “top” refers to how the device istypically oriented relative to the ground. “Bottom” is towards theground, how the device is typically used, e.g. with the legs towardsand/or at the bottom and bowl towards and/or at the top.

“Vertical extent” is defined as “a portion which has a vertical lengththroughout which its cross-sections are substantially identical”.“Horizontal extent” is defined as “a portion which has a horizontallength throughout which its cross-sections are substantially identical”.

The directional descriptors used in this disclosure, such as “top”,“bottom”, “vertical”, “horizontal”, “upper”, “lower”, “above”, and“below” are relative to a typical direction of use with a heat sourcebelow the portion of the vertically-extending passageway substantiallyfarthest from a top portal of the apparatus.

Any device or step to a method described in this disclosure cancomprise, or consist of, that which it is a part of, or the parts whichmake up the device or step. The term “and/or” is inclusive of the itemswhich it joins linguistically and each item by itself. Any element ordescribed portion of the devices shown can be “substantially” as such,if used in the claims in this manner. Where used, “substantially” isdefined as “within a 5% tolerance level thereof.”

DETAILED DESCRIPTION OF EMBODIMENTS OF THE DISCLOSED TECHNOLOGY

A magnetic spinner device using an impeller system to disperse heat andstir contents there-above is disclosed herein. A motor turning theimpeller is offset from a center line extending vertically through thedevice. The impeller, however, is centered with fan blades pushing airdownwards as heat rises from a heat source placed there-below, such asbetween legs which support the impeller and bowl of the device, the bowlbeing used to hold a flask and/or substances to be heated. The turningof the motor is translated to the turning of the impeller by way of tworeels connected by a belt and placed within a lower housing with aremovably connected lower portion. In this manner, the electric parts(the motor) and spared the brunt of the heat by being off-center whilethe heat rises upwards. The simplification of parts leaves less pointsof potential failure compared to the prior art as does the movement ofelectric parts away from being above a heat source.

Embodiments of the disclosed technology will become more clear in viewof the following discussion of the figures.

Discussing FIGS. 1 and 2, FIG. 1 shows a top and side explodedperspective view of a magnetic spinner system in an embodiment of thedisclosed technology. FIG. 2 shows a bottom and side explodedperspective view thereof. From bottom to top, feet 90 support supportlegs 42. The feet are adjustable height and in some embodiments, have ascrew or elongated connector extending upwards through legs 42. The legscan fasten to the feet by rotatably connected to same. A spacer 50attaches to and/or rests on the legs 42. The attachment mechanism, inone embodiment of the disclosed technology, are threaded caps 40 whichthread onto the legs 42 such that the spacer 50 is between the caps 40and legs 42. There can be three, four, five, or more legs withcorresponding feet and portals 52 of the spacer 50. The portals 52 arewhere connector regions of the legs 42 pass through to connect to thecaps 40.

Now discussing the spacer and elements attached thereto, a lower housing70 is abutted and/or connected to and/or held against the spacer 50. Thelower housing 70 can be held in place by way of at least one screwextending there-through and into a threaded portal within the spacer 50.

The lower housing is connected to a motor 80 whose business end (spindle5 which rotates) extends through a lower portal (unnumbered) of thelower housing 70 and connects to a reel 62, which may be a type ofwasher or gear with teeth around the circumference. A belt 60 causesrotation of one of the reels to rotate the other reel. The reel situateddirectly over the motor 80 is off-center. When “center” is used in thisdisclosure, this refers to a vertical line which passes through theportal 54 of the spacer 50 and which is typically equidistant from thelegs 42 and/or passes through the spindle 6 (lower elongated extent) ofthe top housing 30.

The off-center placement of the motor allows heat generated by a heatsource below the device/parts shown in FIGS. 1 and 2 to rise withoutbeing blocked there-above by the motor. The heat generated also causesless harm or strain on the motor compared to a centrally-position motor,since the heat can extend upwards more centered than the motor ratherthan being directly under the motor.

Returning now to the lower housing, the lower housing 70 is held againsta lower side of the spacer 50 by way of a plurality of screw 82, 84extending through a plurality of holes 86, 88 therein. The top housing30 has a lower spindle 6 which extends into a portal 15 in one of thereels 62. Washers 32, 34, and 36, which are above, within, and below theportal 54 of the spacer 50 (in some embodiments) reduce friction betweenthe top housing 30 and the spacer 50, allowing the upper housing 30 tospin as the reels 62 spin. The upper housing 30 is centered at thespindle 6. The upper housing comprises a top portal which is discussedin more detail below.

The lower housing 70 further has a removably attached lower portion 72.The lower portion 72, in the embodiment shown, has a planar sectionsurrounded on three sides by a lip, such that the lip forms a sidewall.The lower portion 72 may be attached to the lower housing 70 by way of aplurality of screw 74 and a plurality of holes 76 such that a bottommostedge of the planar section of the lower portion 72 forms a substantiallyflat, unbroken surface with a bottommost edge of a lowermost portion ofthe lower housing 70.

Within the top portal are wider sections 1 and 2 as well as a narrowsection 4, the narrow section 4 being made narrower, in embodiments ofthe disclosed technology, by a flange extending into what wouldotherwise be a rectangular portal. A bottom side of the upper housing 30has an indented region surrounded by, or mostly by, or partially by, alip 3. The lip 3 can be of any size or shape and prevents rectangularprisms or other shaped upper magnets from falling into the indentedregion.

In the embodiment shown, two magnets 22 and 24, in shapes of rectangularprisms, are inserted within and/or sized to be inserted within the widersections 1 and 2. The magnets 22 and 24 are spaced apart, leaving aspace in the center of the upper housing allowing heat to risethere-above unhindered by the magnets at the center line/center area ofthe devices (e.g. a vertical line equidistant from the legs 42 andpassing through a central point of the portal 52).

The magnets 22 and 24 are sized such that in at least one orientation,and in some embodiments, two orientations, and in some embodiments,three orientations each 90 degrees offset from one of the otherorientations, the magnets are unable to rest flat within the indentedregion on the lip 3. A plate 26 fits within the indented region suchthat a most-elongated and second-most-elongated distance at right orperpendicular angles to each other are normal to the vertical center.The magnets 22 and 24 abut the plate 26, magnetizing the plate 26 suchthat a magnetic field extends across the plate 26. This magnetic fieldis stronger than the two magnets separately as it is joined into asingle extended magnetic field, comparatively. It should be understoodthat any magnetic configuration can be used in other embodiments of thedisclosed technology as long as the magnets are able to turn an impellerby way of magnetic force.

A bowl 20 is situated above the elements 1 to 4 and 28 to 90 inembodiments of the disclosed technology. The bowl can have a flask 27,glassware, or other device held therein along with a substance (solid,liquid, or combination thereof) to be heated and/or spun (stirred). Theheat rising upwards can extend vertically with minimal blockage by partsbetween the bowl 20 and the heat source (not shown). These parts, insome embodiments, which are at the vertical center line are limited to,in some embodiments, the bowl 20, the plate 26 (which is made relativelythin and has a very low heat capacity), the upper housing 30, one of thereels 62, the lower housing 70, and the lower portion 72 of the lowerhousing 70. The motor 80 and magnets 22/24 are outside of the verticalcenter in such embodiments of the disclosed technology.

Referring now specifically to FIG. 2, fan blades 38 are shown which spinwith the upper housing 30 causing air, in some embodiments, to be pusheddownwards, causing a more even flow of upward air towards the bowl 20.The spindle 6 of the upper housing 30, in the embodiment shown, hasmultiple stacked portions, each in shapes of cylinders with differentradii. An uppermost cylinder of the spindle 6, in the embodiment shown,has a larger radius than a portal of the washer 36, such that when thedevice is assembled, a space exists between an uppermost edge of thewasher 36 and a lowermost edge of the fan blades 38 and/or a lowermostedge of the upper housing 30.

FIG. 3 shows a top and side exploded perspective view of a spacer,washers, top housing, plate, magnets, and caps thereof. FIG. 4 shows abottom and side exploded perspective view of a spacer, washers, tophousing, plate, magnets, and caps thereof. In the embodiment shown, eachcap 40 has a threaded spindle 44 extending upwardly from a top-mostplanar surface thereof, such that when the device is assembled, eachspindle 44 extends into a respective hole 46 within a bottom-most planarsurface of the bowl 20. This system of matched spindles 44 and holes 46holds the caps 40, and by extension the legs 42 and the spacer 50,substantially stationary with respect to rotational movement of thespindle 5 of the motor 80, such that the legs 42, caps 40, and spacer 50substantially do not rotate with rotation of the spindle 5 of the motor80. In other embodiments, this prevention of rotation may beaccomplished by other similar systems, such as the use of spindlesextending upwardly from an upper planar surface of the spacer 50 and/ora different number of spindles. The spindles may be unthreaded.

The upper housing 30 is connected to the spacer 50 by way of threewashers 32, 34, 36. In the embodiment shown, the spacer 34 has aninterior tubular section, at least a portion thereof surrounded by, andfunctionally connected to, a ring. The interior tubular section has anupper portion 110 and a lower portion 120, the two portions beingseparated from each other by way of a lip 130. The upper and lowerinterior portions 110, 120 are shaped to receive, respectively, thewasher 32 and the washer 36 (which may be identical).

The upper housing 20 has a spindle 6 which passes through centralportals within washers 32, 34, 36, and central portal 54 of the spacer50. Portions of the spindle 6 are of a width and/or diameter which islarger than the central portal of the washer 36, such that a gap existsbetween a lowermost side of the upper housing 30 and an uppermost sideof the washer 36. This gap allows movement of the upper housing 30, andfan blades 38 attached there-to, without necessarily causing othercomponents, such as washers 32, 34, and 36, to move.

FIG. 5 shows a top and side exploded perspective view of a belt, reels,lower housing, screws, and motor thereof. FIG. 6 shows a bottom and sideexploded perspective view of a belt, reels, lower housing, screws, andmotor thereof. A lower housing 70 has sidewalls and a floor with portalstherein. A lower portion 72 of the lower housing 70 has an extendedplanar section partially surrounded by a lip. An upper side of the lipand a side of the extended planar section not surrounded by the lip areshaped to abut, respectively, lower sides of a portion of the sidewallnot functionally connected to the floor of the lower housing 70 and aplanar side of the floor. Thus, when the lower housing 70 and the lowerportion 72 are connected, the planar section of the lower portion 72lies substantially flush against the floor of the lower housing 70.

The lower portion 72 is removably attachable to the lower housing 70. Inthe embodiment shown, this attachment is by way of screws 74 extendingthrough threaded holes 76. In other embodiments, the attachment may beby way of other removable attachments. “Removable attachments” and“removably connected” are defined as attachments and/or connectionswhich may be removed and reattached at least 1000 times without beingbroken and/or significantly deformed.

In the embodiment shown, when the lower portion 72 is removablyconnected to the lower housing 70, the joint component of the lowerplanar extent of the lower portion 72 and the floor of the lower housing70 has substantially no holes therein excepting holes for screws and fora spindle 5 of a motor 80.

A pair of reels 62 and a belt 60 are sized to fit adjacently within thelower housing 70. When the lower portion 72 is removably connected tothe lower housing 70, both reels 62 rest upon the lower planar extent ofthe lower portion 72 and the floor of the lower housing 70. The reels 62have circumferences with teeth, and the belt 60 has corresponding teeth,such that when the reels 62 are connected by way of the belt 60,movement of one of the reels 62 causes the other reel 62 to turn by wayof the belt 60. In various embodiments of the disclosed technology, thereels and/or belt may take forms of any pair of cylindrical structuresshaped and positioned such that the turning of one causes the turning ofthe other.

FIG. 7 shows a top and side perspective of a top housing, washers,reels, belt, lower housing, and motor thereof in an embodiment of thedisclosed technology. FIG. 8 shows a bottom and side perspective of atop housing, washers, reels, belt, lower housing, and motor thereof inan embodiment of the disclosed technology. The spindle 5 of the motor 80extends through a portal in the floor of the lower housing 70 andthrough a central portal 15 of one of the reels 62. In the embodimentshown, the spindle 5 extends through a central portal 15 of a reel 62which is furthest from a central axis of the central portal 54 of thespacer 50. Thus, turning of the spindle 5 of the motor 80 causes thereel 62 through which it passes, and thus both of the reels 62 and thebelt 60, to turn as well. The spindle 5 and the motor 80, in theembodiment shown, are removably held in position with respect to thelower housing 70 and/or the spacer 50 by way of a plurality of screws82, 84.

The spacer 50 and the upper housing 30 may be attached to the lowerhousing 70 by way of screws or other removable connectors. In suchembodiments, rotation of the spindle 5 of the motor 80 has the followingeffect: a reel 62 located vertically above the spindle 5 and throughwhich the spindle 5 passes rotates, which causes the belt 60 and thusthe second reel 62 to rotate as well. Rotation of the second reel 62causes both the spindle 6 and the upper housing 30 to rotate as well. Atthe same time, the lower housing 70, spacer 50, and washer 34 remainsubstantially stationary. In various embodiments, the washers 32 and 36may rotate and/or remain stationary, depending on a distance andfrictional constant between an inner surface of washer 34 and an outersurface of washers 32 and 36.

FIG. 9 shows a top and side perspective view thereof. FIG. 10 shows abottom and side perspective view thereof. In the embodiment shown, ahorizontal width of the bowl 20 is a largest width of the device.Furthermore, an axis passing perpendicularly through a central point ofa horizontal planar cross-section of the the bowl 20 passes through asubstantial center of the upper housing 30; the plate 26 (not shown); aspace between the prisms 22, 24 (not shown); the spacer 50; a spacebetween the legs 42 thereof; the flask 27; and a mouth 102 of the flask27.

A flask cover 100 is removably attachable to the flask 27 in theembodiment shown. The flask cover 100 may be shaped to cover a majorityof a portion of the flask 27 which extends above a highest plane of thebowl 20. The flask cover 100 may have an opening 104 to accommodate themouth 102 of the flask 27. The flask cover 100 may be made of aninsulating material, such that when the flask 27 and/or contents thereofis/are heated to a particular temperature range which burns human skin,the flask cover 100 remains at a temperature which does not burn humanskin.

FIG. 11 shows a back elevation view thereof. FIG. 12 shows a right sideelevation view thereof. FIG. 13 shows a left side elevation viewthereof. FIG. 14 shows a front elevation view thereof. FIG. 15 shows atop plan view thereof. FIG. 16 shows a bottom plan view thereof. FIG. 17shows a cutaway front elevation view thereof. In various embodiments, aheat source, such as a flame, a fire, or other sources of heat known inthe art, is placed at a point vertically below the flask 27 and/or atleast a portion of the device. The heat source may be placed verticallyabove and horizontally offset relative to the motor 80 and/or may beplaced at a point between the legs 42. In some embodiments, the heatsource may be centered between the legs 42.

In various embodiments, an impeller 29 is located within and/or attachedto the flask 27. The impeller 29 is constructed of a ferromagneticmaterial and/or is a magnet, such that rotation of the magnetic prisms22, 24 and the plate 26 located within the upper housing 30 causes theimpeller 29 to rotate commensurately. The impeller 29 is sufficientlyfixed to the flask 27 that rotation thereof, caused by rotation of themagnetic prisms 22, 24 and the plate 26 located within the upper housing30, causes the flask 27 to rotate commensurately, thus stirring contentsthereof.

In embodiments, when the heat source is placed below the flask 27 andthe spindle 5 of the motor 80 is rotating, heat from the heat sourceextends upward toward the bowl 20 and/or the flask 27 and/or contentsthereof. The heat from the heat source may be of sufficient quantitiesto alter a temperature of the bowl 20 and/or of the flask 27 and/or ofcontents thereof. A combination of heating by the heat source andstirring by way of the impeller 29 thus causes contents of the flask 27to be evenly heated. The heat from the heat source is also pusheddownward by rotation of the fan blades 38, caused by rotation of theupper housing 30. The fan blades dissipate heat above the spacer 50 suchthat the heat has turbulent flow outwards and up towards the entire baseof the bowl 20, making for even heating at the bottom side of the bowl20. This combination causes a more even heating of the bowl 20 and/orthe flask 27 and/or contents thereof.

FIG. 18 shows a top and side exploded perspective view of a top housingand washer thereof. FIG. 19 shows a bottom and side exploded perspectiveview of a top housing and washer thereof. FIG. 20 shows a frontelevation view of a top housing and washer thereof. FIG. 21 shows acutaway front elevation view of a top housing and washer thereof. FIG.22 shows a top plan view of a top housing and washer thereof. FIG. 23shows a bottom plan view of a top housing and washer thereof.

The upper housing 30 is circular, in embodiments of the disclosedtechnology, so that it can rotate evenly. The centrifugal force causedby its rotation causes the magnetic prisms 22, 24 to be forced towardsouter edges of the upper housing 30. The magnets 22, 24 (not shown) fitinto each of the wider regions 1 and 2 respectively. The narrower region4 has flanges extending towards each other, as shown, which prevents themagnets 22, 24 in cavities 1 and 2 from moving towards each other.

The lip 3 is sized to fit a plate such as a metal and/or magnetizableplate 26 (not shown) having low heat capacity (such as 1000 Joules perkilogram degree Celsius).

The spindle 6 of the upper housing 30 can have a plurality of descendingsections of varying circumferences which are each sized to fit in awasher, such as washers 32, 34, and 36, while the end of the spindle isrotatably connected within one of the reels 62. A separation is thusmaintained between a lowermost part of the plurality of fan blades 38attached to the upper housing 30 and between an uppermost edge of anywasher 32, 34, 36, allowing the fan blades 38 to rotate substantiallywithout resistance.

The washer 34 has interior receptacles 110, 120 to accommodate washers32 and 36, respectively. The receptacles 110, 120 are separated by a lip130. Washer 32 and/or washer 36 may extend from the lip 130 to a pointbeyond, respectively, an uppermost and/or a lowermost horizontal planeof the washer 34.
